Central Test Unit for Emergency Lighting

Manufacturer : GARO

The CTU emergency lighting test switch is designed to test the function of emergency luminaires. A key switch is used to interrupt the supply to the luminaires for a pre-programmed period of time. At the end of the time period the supply to the luminaires is automatically re-instated. The result is that there is no risk of depleting the batteries in the emergency fitting.The unit will power up with the SUPPLY ON lamp illuminated—the supply will be connected to the output. Turn and release the key switch to select the 10 minute test interval. Turn and release again to select the next test interval—the supply will be disconnected from the output for the duration of the test. To cancel a test, turn and release the keyswitch until the SUPPLY ON lamp illuminates. Three pre-programmed test intervals are available:

• 10 minutes.
• 1 hour.
• 3 hours
